PBN as it is commonly referred to stands for Pyrolytic Boron Nitride and is produced by a process called CVD Chemical Vapour Deposition, with very good resistance to thermal shock. Our Pyrolytic Boron Nitride is always manufactured to our customer’s specific requirements on shape and size.
PBN is very attractive to many industry sectors, such as:
With the advent of the 5G era, zirconia ceramics have become the new favorite material for mobile phone backplanes.
By the end of 2018, 154 mobile operators around the world are conducting 5G technology testing or testing, and the number of countries participating in 5G has expanded to 66. With the advent of the 5G era, the mobile phone industry will usher in a new round of changes, and the mobile phone backplane market is facing a reshuffle. Among them, zirconia ceramics stand out in a new round of technical reshuffles.
Advantages of zirconia ceramics as raw materials for mobile phone back sheets.
The 5G era requires faster signal transmission, which is 1~100 times that of 4G. 5G communication will use the spectrum above 3Ghz, and the wavelength of the millimeter-wave is shorter. Compared with the metal backplane, the ceramic backplane has no interference to the signal and has unparalleled superior performance of other materials, which is favored by mobile phone manufacturers.
Comparison and difference between several major mobile phone backplane materials.

Among all ceramic materials, zirconia ceramics have the advantages of high strength, high hardness, acid and alkali corrosion resistance and high chemical stability, as well as scratch resistance, no signal shielding, excellent heat dissipation performance, good appearance, etc. Features, therefore become a new type of mobile phone body material after plastic, metal, glass. At present, the application of zirconia ceramics in mobile phones is mainly two parts of the backboard and the fingerprint identification cover.
The electrostatic microporous ceramic chuck is a key part of the deep silicon etching machine. The electrostatic adsorption technology used is an advantageous technology that replaces the traditional mechanical clamping and vacuum adsorption methods. It has a wide range of fields in semiconductors, panel displays, and optics, application.
Features of electrostatic microporous ceramic chucks:
1. Can be used simultaneously in the atmosphere and vacuum environment;
2. Can adsorb conductors, semiconductors, insulators, and porous materials;
3. Simplified clamping and handling mechanism, low energy consumption for electrostatic adsorption;
4. The adsorption force is uniform, and there will be no local force during adsorption;
5. Light and soft support for large-area thin film, and there will be no scratches and wrinkles during adsorption;
6. It can be opened and closed quickly, and no potential is generated on the back of the object, and the surrounding dust is not absorbed.
Application fields: vacuum bonding in the panel industry, semiconductor chip packaging, microelectronic integrated circuits, precision optical component manufacturing, solar photovoltaic.
Pyrolytic boron nitride is a grade of hexagonal boron nitride. It is produced by the chemical vapor deposition process to create its solid body and all the boron nitride crystals grow parallel to the surface on which the vapor is deposited.
INNOVACERA produces PBN by customized design. The thickness ranges from 0.2 to 4mm. And the max dimension is around 150x150mm or Diameter of 300mm. The tolerance usually is +/-0.05mm. If you request higher tolerance, then we can evaluate your design first.
Features of PBN
* Good thermal shock resistance
* High insulation resistance
* Non-wetting
* Non-toxic
Due to its features, PBN is very often used in a vacuum environment as a base plate, insulator plate, etc. If you’re looking for a material that can work in a vacuum or MBE system, please don’t hesitate to contact us for PBN.
Our ceramic scalpel combines the advantage of scalpel and craft knife. Its slim and flat structure is capable of reaching into tight spaces. We use quality zirconia ceramic with features of non-rust, non-conductive, and chemically inert. The blades are safe up to 900℃.
Ceramic Blades have following advantages:
Boron Nitride is an ideal material for atomizer nozzle due to its high strength, high melting point, high toughness, outstanding thermal shock resistance, excellent machinability, and low-friction properties.BN nozzles for the atomizing process may ensure a continuous flow with no blockage or breakage.
INNOVACERA provides different grades of BN materials as below. The best choice for metal powder gas atomization should be BN99, BN-B, or BN-D.
It is an advanced ceramic material with a high melting point, is tough enough to prevent cracks, has high thermal shock resistance, and is easily machinable. In addition, molten metals cannot ‘wet’ the surface of boron nitride, which means that it is not easily clogged during the atomization process.
Under a high vacuum, boron nitride can survive up to 1,750 °C. A gas atmosphere can push this even further to 1,900 °C. This means that boron nitride will remain solid through the melting of most metals. Boron nitride has a very low thermal expansion. Together with the high heat conductivity, this ensures that the material has very high shock resistance. It can easily withstand the rapid gradations in temperature inside the atomizer. It does not break or crack under thermal stresses.
Xiamen Innovacera Advanced Materials Co., Ltd can provide thick film metalizing ceramics.
The ceramic parts do metalized coating or plating. Thick film coatings include Molybdenum-Manganese (Mo-Mn) providing excellent adhesion to ceramic parts. This can be followed by a barrier diffusion layer of electrolytic pure Nickel (Ni). The third layer of gold (Au) or other precious metal, results in a tightly sealed ceramic to metal assembly ready for the soldering or brazing process.
